I recall reading many articles prior to the Iraq war about Ansar al-islam and how it was treating the people within its range. It was establishing a mini-taliban state around the camp, and villagers who wore western clothes or who violated the extreme sharia laws that al-qaida demands were being murdered. Was that false? What is the source of your all-knowing information?
Yeah, a "mini-taliban state" - from the goat pen over to the creek.
The Kurds could've crushed this group like a bug. They were in a tiny, isolated area snug up against the Iranian border. They were as likely to "control the area brutally" as the Blue Man Group.
